From a327dee0f40bcdebaba1a3e47f2b9f1ceb970d2a Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 23 Jul 2014 06:55:21 -0600 Subject: dm: Add child_pre_probe() and child_post_remove() methods Some devices (particularly bus devices) must track their children, knowing when a new child is added so that it can be set up for communication on the bus. Add a child_pre_probe() method to provide this feature, and a corresponding child_post_remove() method.
